Thought I'd write up a guide for this because it took me some tweaking to get working, and I couldn't find this all in one place and had to figure some of it out myself. SMAC is one of the most critically acclaimed Sid Meier games around and I've been itching to play it after reading everything Reddit has to say about it.

I'm working with the .exe installer I purchased from GoG.com, available for only $2.99 for the next few days, I don't know if this will work for the CD version as I know GoG tweak their games slightly to work with modern computers. [Link].

Codeweavers Crossover is a fantastic app that I use almost every day to avoid having to reboot into Bootcamp, well worth the $59 they ask (cheaper than a new copy of Win7 for Bootcamp), and I'm using version 12.0, released earlier this month. [Link]

I'm also using Mac OS 10,7,5 and a mid-2009 Macbook Pro.

First step is to do the basic install. Pick "other application" from the menu of available choices, select the file "setup_sid_meiers_alpha_centauri_2.0.0.19.exe" as the installer file, and a new Windows XP installer bottle. [Screenshot].

Once that's done, some people are reporting that the game just plays for them. If it does, that's great, but for me it wasn't working.

Go back to Crossover, and select Configure>Manage Bottles from the menu. From the window that pops up, select the Advanced tab, and then press the "Open C: Drive in Finder" button. [Screenshot]

From the window it opens, select GOG Games>Sid Meier's Alpha Centauri>Alpha Centauri.Ini and open that file in TextEdit. Make sure the following lines are present in the file

ForceOldVoxelAlgorithm=1
DisableOpeningMovie=1
DirectDraw=0

Save the file and close it. From there, go to the Control Panel tab, and select Wine Configuration, and click Launch Selected Item. [Screenshot]

From the Wine Configuration menu, in the default tab change the Windows Version to Windows 98. [Screenshot]

Then, select the Graphics tab, and make sure that "Emulate a virtual desktop" is unchecked. [Screenshot]

Select OK to close the window, and from that point, the game works for me, and should do for you as well! [Screenshot]

Please let me know if this works for anybody else, I hope it's helpful!

Wasn't there a fan project that made a carbonized shell for Alpha Centauri? I remember it ran under 10.6 as long as you had the original data files, but I don't know if it was technically still PowerPC or not.
